Source Transfer Switch (STS)
This STS product is designed with two independent power inlets to supply power to the load from a primary power source. Should primary power source fails, the secondary will automatically back up the connected equipment without any interruption. The transfer time from one line to another is seamless to the connected equipment. After switching to a secondary power source, the STS can also switch power back to the primary input when power to the primary input is restored.
